Description

Cylindrical Lock and Key Combination The present invention relates to a cylindrical lock and key combination. Specifically, the present invention relates to a disc tumbler cylinder lock and key combination, wherein the disc tumbler cylinder lock is provided with a rotation limiter. In a disc tumbler cylinder lock, a tumbler disc is used to analyze the specific code of a key and open the lock. Inserting a key into the disc tumbler cylinder lock does not clarify the code yet. Only by turning the key, starting the rotation of the tumbler disc according to the cuts of the key (also called combination cuts), can the key code be clarified therefrom. Once the key code is clarified and the key continues to be turned, the disc tumbler cylinder lock is unlocked. That is, continuing to turn the key after clarifying the key code causes the rotation of the rear end of the disc tumbler cylinder lock, which can be associated with a locking rod or connected to the locking rod via a locking mechanism. The rotation limiter is a mechanism that prevents an incorrect key inserted into the disc tumbler cylinder lock from rotating in the disc tumbler cylinder lock so that the tumbler basically does not rotate out of the basic position. The rotation limiter also prevents the lock-matching key from rotating unless the lock-matching key has been fully inserted into the lock core. In this situation, even without releasing the lock, the rotation of the key can cause the tumbler disc to rotate out of the engagement basic position of the tumbler disc. The basic position refers to the condition in which the key can be inserted into the cylindrical lock (and can also be pulled out of the cylindrical lock). In the basic position, the cylindrical lock is in a locked state. The rotation limiter allows the correct key to rotate in the cylindrical lock as long as the key has been fully inserted therein. For example, patent publication FI 108308 discloses a known rotation limiter for a disc tumbler cylinder lock. The rotation limiter includes a main body and a housing. The housing is integrated with the inner cylinder of the disc tumbler cylinder lock. The main body has a key profile opening in the middle, through which the key can be inserted into the cylindrical lock. On each side of the key profile opening are limiter mechanisms along the same straight line. The limiter mechanism consists of a spring and balls at its two ends. The key matching the disc tumbler cylinder lock has a mating surface for the balls of the limiter mechanism. The mating surface is a recess in the surface of the key. When the correct key is present in the key cylinder, the key can be rotated thereby to displace the tumbler disc to the correct position to release the locking. Therefore, the inner cylinder can rotate as the key continues to rotate. Thus, the rotation limiter improves the operational reliability of the disc tumbler cylinder lock. The lock may also include a guiding element disposed in the keyway, which is jointly established by the key openings contained in the disc described in FI 108308. The guiding element includes two guide rails and a yoke between the guide rails. The yoke is located at the inner end of the disc cylinder lock and thus fixedly engages the guide rails with each other. In other words, the guiding element may be a guide rail bent 180 degrees in the middle. The guiding element is conventionally supported on the rotation limiting member in such a way that the guiding element also rotates continuously when the key is rotated in the lock. The guiding element controls the insertion of the key into and removal from the lock and also serves as a housing to prevent manipulation. Additionally, by itself, the guiding element also helps the lock to match the contour of the key. Publication FI 124224 discloses another rotation limiter for a disc cylinder lock. The rotation limiter includes a limiting mechanism and a locking mechanism arranged in a straight line. The limiting mechanism and the locking mechanism are arranged in a straight line such that the limiting mechanism is on the other side of the key profile opening and the locking mechanism is on the opposite side of the key profile opening. The key used with this lock has a moving element that is in a straight line with the limiting mechanism and the locking mechanism when the key has been inserted into the lock. Pin tumblers are used in pin cylinder locks. The pin tumblers provide a specific key code and prevent the inner cylinder from rotating relative to the outer structure of the pin cylinder lock when the correct key is not used. Thus, the previously known disc cylinder lock solutions and pin cylinder locks provide good security protection against manipulation, but there is still a need for improved protection solutions. One object of the present invention is to improve the quality of the cylinder lock against manipulation and to increase the security of the cylinder lock and key combination. This object is achieved as presented in the independent claims. Various embodiments of the present invention are presented in the dependent claims. The combination of the cylinder locks 1, 40 and keys 2, 46 according to the present invention has cylinder locks 1, 40 that include an inner structure configuration that includes key profile openings 21, 43. The keys 2, 46 include a movable element 5. The keys 2, 46 also include a slot 16 that is transverse to the longitudinal axis of the shaft of the keys 2, 46, and the movable element 5 is configured to move along the slot 16. The inner structure configuration includes a locking mechanism that includes a roller 26, a locking member configuration 25, and a return spring configuration 27. The roller 26 includes a guiding surface 35 at the end 35A of the roller, which end is in the key profile openings 21, 43. The roller 26 is also connected to the locking member configuration 25 and the return spring configuration 27. The return spring configuration is configured to rotate the roller 26 towards the locking position of the roller, in which the roller is configured to cooperate with the locking member configuration 25 to prevent the inner structure configuration from rotating. The internal structure arrangement has at least one second guiding surface 29 on at least one side of the key profile opening 21 to move the movable element 5 along the slot 16 when the key 2 is inserted into the cylinder lock 1, so that when the key is further pushed into the cylinder lock, the movable element 5 is in a position for contacting the guiding surface 35 and rotating the roller 26. The internal structure arrangement further includes at least one third guiding surface 36 on at least one side of the key profile opening 21 to move the movable element 5 along the slot 16 and, with the guiding surface 35, rotate the roller 26 to the open position when the key is further pushed into the cylinder lock. The guiding surface 35 is further configured to move the movable element 5 along the slot 16 when the key 2 is pulled away from the cylinder lock 1, and in response to this movement of the movable element 5, the roller 26 is configured to rotate towards its locking position. FIG. 1 shows an example of the disc bolt cylinder lock 1 of the present invention and its key 2 in an exploded view. FIG. 2 shows the key 2 in more detail. FIG. 3 shows a cross-sectional view of the key. FIG. 4 shows a cross-sectional view of the shaft 18 of the key. The disc bolt cylinder lock includes a main body part 6, and other parts are assembled on the main body part when the lock is constructed. The main body part has a hole 6A for the key at its front end. This hole, together with holes in other parts, forms a key channel into which the key will be inserted to unlock the disc bolt cylinder lock. As can be seen from FIG. 1, the disc bolt 8, the intermediate disc 9, and other possible components such as the drilling protection disc 14 include holes for the key and the key channel. The disc bolt and the intermediate disc are alternately arranged in the disc bolt lock core. The intermediate disc enables each bolt disc to rotate in a way that other bolt discs 8 do not rotate together due to friction. The intermediate disc includes an abutting structure placed against the internal structure 7 of the disc bolt cylinder lock. FIG. 1 illustrates the internal structure of the disc bolt cylinder lock, which is the inner cylinder 7, but it is also possible to construct some other type of internal structure where, for example, the intermediate discs are connected to each other and to an independent bottom element. For example, WO2016075363 proposes this type of internal structure, which can be modified / applied as the internal structure for the disc bolt cylinder lock included in the combination according to the present invention. The internal structure / cylinder 7 has a rear end that includes an attachment element for attaching a locking rod or, for example, a torsion rod to the disc bolt cylinder lock. The rear end and its parts are not shown in detail in FIG. 1 because their structures are known. The inner cylinder has a slot for the bolt pin 10. The bolt pin prevents the rotation of the key 2 unless the bolt has been rotated in such a way that the peripheral notches 8A of the bolts together with the respective notches of the intermediate disk 9 form a continuous groove. The continuous groove enables the bolt pin 10 to move inwards in the disk cylinder lock after the specific code of the key has been clarified and the key 2 to rotate. In the present disclosure, inwards means the direction towards the central region of the key passage of the disk cylinder lock, which region contains the central axis B (Figure 5) in the disk cylinder lock. Outwards from the disk cylinder lock means the opposite direction, i.e., away from the central region of the key passage. The spring 12 ensures the operation of the bolt pin as required. The saddle part 11 can be used between the spring and the bolt pin 10. The combination of the disk cylinder lock 1 and the key 2 according to the present invention includes a rotation limiting member 3, also called a rotation limiter, for the key and the guiding element 4 in the disk cylinder lock 1. The cylinder lock may also have a return pin 13 to guide the bolt disk 8 back to the basic position when the key is also rotated back to the basic position. The rotation limiting member is shown in Figures 5 to 12. The rotation limiting member includes a main body 3B having a key profile opening 21 and a housing 3A that at least partially surrounds the main body. The disk cylinder lock 1 also includes a guiding element 4, and the key 2 includes a movable element 5. The key also has a combination cut 15 that forms the key code in a known manner. As can be mentioned, especially in Figure 1, the internal structure configuration of the cylinder lock may include different parts, such as the inner cylinder 7, the bolt 8, the rotation limiter 3, the guiding element 4, the bolt pin 10, etc. The key 2 includes a slot 16 that is transverse to the longitudinal axis A of the shank 18 of the key 2 and also passes through the shank of the key. The movable element 5 is configured to move along the slot 16. Thus, the movable element can move in the transverse direction relative to the longitudinal axis A. The main body 3B includes a locking mechanism that includes a roller 26, a locking member configuration 25, and a return spring configuration 27. The roller 26 includes a guiding surface 35 at the end 35A of the roller. This end is in the key profile opening 21. The roller 26 is also connected to the locking member configuration 25 and the return spring configuration 27. The return spring configuration is configured to rotate the roller 26 towards the locking position of the roller. The locking member configuration 25 is also connected to the housing 3A. The roller is configured in its locking position to cooperate with the locking member configuration 25 and the housing 3A to prevent the rotation of the main body 3B. The housing has a hole 3C for the key and also for the guiding element 4. The housing is non-rotatably connected to the inner cylinder 7 using a groove 3D. The body 3B has second guiding surfaces 28, 29 on the side surface of the key profile opening 21 to move the movable element 5 along the slot 16 when the key 2 is inserted into the cylinder lock 1, so that the movable element 5 is in a position for contacting the guiding surface 35 and rotating the roller 26 when the key is further pushed into the cylinder lock. Before the key is pushed into the lock core, the movable element 5 can be in any position at the slot 16. FIGS. 9, 10 and also FIG. 6 illustrate the situation where the key shaft has been partially pushed into the lock core and the shaft portion of the movable element 5 positioned therein is exactly inserted into the lock core 1. The second guiding surfaces 28, 29 drive the movable element to a position where the movable element can contact the guiding surface 35 of the roller when the key is further inserted into the lock core. When the movable element 5 pushes the guiding surface 35 by the pushing movement of the key, the roller 26 starts to rotate against the force of the return spring arrangement 27. FIGS. 7 and 11 illustrate the situation where the roller 26 has been partially rotated. The body 3B further includes a third guiding surface 36 on the side surface of the key profile opening 21 to move the movable element 5 along the slot 16 and, with the guiding surface 35, rotate the roller 26 to the open position when the key is further pushed into the cylinder lock. The open position is shown in FIGS. 8 and 12. It is noted that the third guiding surface 36 drives the movable element 5 along the slot 16, that is, drives the movable element in the transverse direction relative to the longitudinal axis A of the shaft of the key 2. The body 3B further includes a fourth guiding surface 28B (FIG. 5), which is configured to work with the guiding surface 35 to move the movable element 5 along the slot 16 when the key 2 is pulled away from the cylinder lock 1, and in response to this movement of the movable element 5, the roller 26 is configured to rotate towards its locking position. The return spring arrangement ensures that the roller rotates to the locking position. The movable element 5 has a circular profile at least at its ends. The ends provide protrusions at the side of the key shaft 18 and can contact the guiding surfaces 35, 28, 28B, 29, 36 described above. The embodiments in the figures show that the movable element has a circular profile. However, the profile of the movable element can also be another form, especially in the middle part of the movable element, such as a rectangular profile. As can be seen, the basic shape of the movable element 5 can be a short pin. The slot 16 can have a groove 19 in the middle of the slot, and the movable element 5 has a boss 20 aligned with the groove. In this way, the movable element is held in the slot 16 and is not released from the key 2. For easy placement, the key 2 can include an insert body 17 installed in the through hole. The insert body 17 includes the slot 16 in which the movable element 5 is located. The second guiding surfaces 28, 29 are inclined surfaces with respect to the longitudinal axis B of the key profile opening 21, and are inclined toward the end side 21A of the key profile opening when viewed from the outside of the key profile opening. The third guiding surface 36 is an inclined surface with respect to the longitudinal axis B of the key profile opening 21, and is inclined toward the second end side 21B of the key profile opening when viewed from the outside of the key profile opening. Therefore, when the key 2 is inserted into the lock cylinder 1, the movable element 5 is first driven toward the end side 21A of the key profile opening, and later toward the second end side 21B of the key profile opening. This means that when the key is inserted into the lock cylinder, the movable element 5 is driven to move back and forth in the slot 16. The third guiding surface 36 can be formed by the end of the guide rail 4A of the guiding element 4 shown in FIGS. 10 to 12. The guiding element is connected to the main body 3B. Another way to provide the third guiding surface is to have an independent protrusion on the side surface of the key profile opening, and in this embodiment, it is convenient that the surface of the protrusion toward the center of the key profile opening 21 matches the inner surface 4C of the guide rail 4A. The yoke 4B connects the guide rail 4A of the guiding element 4 at the inner end of the disc cylinder lock. The fourth guiding surface 28B is an inclined surface with respect to the longitudinal axis of the key profile opening 21, and is inclined toward the second end side 21B of the key profile opening when viewed from the outside of the key profile opening, and is the side surface of the key profile opening 21 opposite to the end 35A of the roller 26. When the key 2 is pulled out of the lock cylinder 1, the fourth guiding surface 28B works together with the guiding surface 35. The guiding surface 35 on the roller 26 has a concave shape, so it has a circular edge 35B upward with respect to the middle part 35C of the guiding surface 35, as shown in the figures. This shape is convenient for driving the movable element 5. As shown in the figures, the guiding surface 35 is the side surface of the notch 34 on the end 35A of the roller. The roller 26 also has a recess 32, which is arranged toward the locking member arrangement 25 in the open position of the roller 26. In the open position, the recess 32 allows the locking member arrangement 25 to move away from the housing part 3A, in which case the main body 3B can rotate relative to the housing part 3A and the main body part 6 together with the inner cylinder 7. When the roller is in the locked position, the recess is not in line with the locking member arrangement 25, in which case the locking member arrangement 25 is partially in the recess 3E of the housing part, and the main body 3B cannot rotate relative to the housing part, and thus the inner cylinder 7 cannot be rotated to clarify the key code. The locking member arrangement 25 can include at least two balls 25, but the locking member arrangement can also be made in different ways. For example, the locking member arrangement includes a pin with a circular end. The roller may have a stopper 33 to limit the rotation of the roller and the main body 3B. In addition, the roller 26 may also have an annular groove 31 on its surface connected to the recess 32. The annular groove provides more guidance to the locking member arrangement 25. Additionally, the roller may have a groove 30 for the return spring arrangement 27. In the embodiments of the figures, the return spring arrangement 27 may include a torsion spring. Another embodiment of the return spring arrangement 27 includes a return roller and a compression spring. Thus, there are many ways to manufacture the return spring arrangement. In addition to the above-mentioned parts of the main body 3B such as the roller 26, the locking member arrangement 25, and the return spring arrangement 27, the main body 3B may also include an indicator arrangement 22 to indicate the locking state of the cylinder lock. The locking state refers to the condition in which the inner cylinder 7 cannot rotate. Therefore, the key 2 may have a recess 5A for the indicator arrangement 22. The indicator arrangement 22 also functions as a limiting arrangement to limit the rotation of the main body 3B. The indicator arrangement 22 may include two rollers 23 and a spring 24 between the rollers. One of the rollers abuts against the housing 3A. The housing has a recess 3F for the roller. If the key is fully inserted into the cylinder lock, when the key is rotated, the roller on the housing side can move away from the recess 3F of the housing. Figures 13, 14, and 15 illustrate an example of a bolt cylinder lock 40 according to the present invention. Figures 16 and 17 show examples of keys used with the bolt cylinder lock according to the present invention. The bolt cylinder lock 40 has an outer structure 41 in which an inner cylinder 42 is installed. The inner cylinder also has the key profile opening 43 into which the key 46 is inserted when the lock is opened. A portion of the bolt 45 is inside the inner cylinder, as shown in Figure 15. Therefore, in an embodiment of the bolt cylinder lock, the inner structure arrangement includes at least the inner cylinder 42 having the key profile opening 43 and a portion of the bolt 45. The key 46 has parts similar to the examples of Figures 2 to 4, namely the movable element 5 and the slot 16. In addition, the keys 46, 2 may have a groove 19 and an insert body 17, and the movable element may have a boss 20. The inner cylinder 42 (and thus the inner structure arrangement) according to the present invention includes the roller 26, the locking member arrangement 25, and the return spring arrangement 27. Here, the locking member arrangement 25 is also connected to the outer structure 41. Therefore, the roller is configured in its locking position to cooperate with the locking member arrangement 25 and the outer structure to prevent the inner cylinder from rotating. The hole in the outer structure 41 in which the inner cylinder is installed has a recess 44 for the locking member arrangement to hold the roller in its locking position. The bolt cylinder also has the above-mentioned guiding surface 35, at least one second guiding surface 29, and at least one third guiding surface 36. The guiding surface 35 is further arranged to move the movable element 5 along the slot 16 when the key 46 is pulled away from the cylinder lock 40, and in response to this movement of the movable element 5, the roller 26 is arranged to rotate towards its locking position. FIG. 17 shows an embodiment in which the slot 16 passes through the shank of the key 46. In this case, the cylinder lock may have a fourth guiding surface 28B on one side of the key profile opening, and the fourth guiding surface is arranged to work together with the guiding surface 35 to move the movable element 5 along the slot 16 when the key 2 is pulled away from the cylinder lock 1. Another embodiment is that the slot does not pass through the shank of the key. Therefore, the movable element 5 provides a protrusion on one side of the shank of the key. In any case, it is convenient that the profile of the key 46 is such that it has a kind of longitudinal groove, and the protruding part of the movable element is in the longitudinal groove. In this way, the external wear of the movable element 5 is less. Another embodiment is that the movable element 5 has a flange for holding it in the slot 16 that passes through the shanks of the keys 2 and 46. Therefore, this embodiment of the key can be used with a disc cylinder lock and a cylinder lock. As can be mentioned, at least some parts of the cylinder lock and the key according to the present invention and their functions are similar to the corresponding parts and functions in the disc cylinder lock and the key shown above. The present invention improves the security features of the disc cylinder lock / cylinder lock and key combination. Due to the roller 26 and its rotation, the manipulation becomes more difficult, and when the key is inserted into the lock core, the movable element 5 in the key is driven to move back and forth in the slot 16 in the transverse direction relative to the longitudinal axis A of the key 2. The key security is also improved because it is extremely difficult to duplicate a working key. The main body 3B or the inner cylinder 42 has holes and cavities for the parts described in this specification. As mentioned, the key profile opening 21 follows the profile of the keys 2 and 46. Obviously, the present invention is not limited to the examples presented in this disclosure, but the present invention can be implemented in a variety of different embodiments within the scope of the appended claims. 1: Disk bolt cylinder lock / cylinder lock / lock core 2: Key 3: Rotation limiting member / rotation limiter 3A: Housing / housing part 3B: Main body 3C: Hole 3D: Groove 3E: Recess 3F: Recess 4: Guide element 4A: Guide rail 4B: Yoke 4C: Inner surface 5: Movable element 6: Main body part 6A: Hole 7: Inner structure / inner cylinder 8: Disk bolt / bolt disk 8A: Peripheral notch 9: Intermediate disk 10: Bolt pin 11: Saddle part 12: Spring 13: Return pin 14: Drilling protection disk 15: Combined notch 16: Slot 17: Insert body 18: Shaft / key shaft 19: Groove 20: Boss 21: Key profile opening 21A: End side 21B: Second end side 22: Indicator arrangement 23: Ball 24: Spring 25: Locking member arrangement 26: Roller 27: Return spring arrangement 28: Second guide surface 28B: Fourth guide surface 29: Second guide surface 30: Groove 31: Annular groove 32: Recess 33: Stopper 34: Notch 35: Guide surface 35A: End 35B: Circular edge 35C: Intermediate part 36: Third guide surface 40: Cylinder lock / pin bolt cylinder lock 41: Outer structure 42: Inner cylinder 43: Key profile opening 44: Recess 45: Bolt 46: Key A: Longitudinal axis B: Central axis The present invention will now be described in more detail with reference to the accompanying drawings, in which: [FIG. 1] shows an example of a disk bolt cylinder lock and a key of the present invention, [FIG. 2] shows an example of a key of the present invention, [FIG. 3] shows an example of a cross-sectional view of the key in FIG. 2, [FIG. 4] shows an example of a partial view of the shaft of the key in FIG. 2, [FIG. 5] shows an example of a rotation limiter and a guide element according to the present invention, [FIG. 6] shows the rotating element of FIG. 5 in a cross-sectional view, [FIG. 7] shows a cross-sectional view of the rotation limiter in a position where the roller is rotated towards the open position, [FIG. 8] shows a cross-sectional view of the rotation limiter in a position where the roller is in the open position, [FIG. 9] shows an example of the operation of the rotation limiter for the disk bolt cylinder lock of the present invention when the key is inserted into the disk bolt cylinder lock, [FIG. 10] shows the example of FIG. 9 in a cross-sectional view, [FIG. 11] shows an example where the key has been further inserted into the disk bolt cylinder lock, [FIG. 12] shows an example where the rotation limiter is in the open position, [FIG. 13] shows an example of a pin bolt cylinder lock according to the present invention, [FIG. 14] shows another view of the pin bolt cylinder lock according to the present invention, [FIG. 15] shows an example of a side cross-sectional view of the pin bolt cylinder lock according to the present invention, [FIG. 16] shows an example of a key according to the present invention to be used with the pin bolt cylinder lock according to the present invention, and [FIG. 17] shows the example of FIG. 16 in a cross-sectional view. 1: Disk Bolt Cylinder Lock / Cylinder Lock / Lock Core 2: Key 3: Rotation Limiting Member / Rotation Limiter 4: Guide Element 5: Movable Element 6: Main Body Part 6A: Hole 7: Inner Structure / Inner Cylinder 8: Disk Bolt / Locking Disk 8A: Peripheral Notch 9: Intermediate Disk 10: Locking Pin 12: Spring 11: Saddle Part 13: Return Pin 14: Drilling Protection Disk 15: Combined Cut
