Description

Cylinder lock

The present invention relates to a cylinder lock having a rotatable steering disc. More particularly, the present invention relates to a cylinder lock that is rotated by a key having at least one groove in the surface for rotating the steering wheel.

It is known that a cylinder lock using a rotatable steering disc has an inner cylinder mounted inside the cylindrical casing, wherein the steering wheel is located in the inner cylinder. In addition, there is a cylinder lock that does not have an inner cylinder. The keys that operate the cylinder lock typically have transverse cuts to align against the steering wheel as the key is rotated.

In addition, there are other types of cylinder locks that use a rotatable steering member. In such cylinder locks, the steering disk is rotated by a key following a curved path parallel to the axis of the key, the surface of the shaft having at least one curved groove in the surface. The steering disk has a projection at the edge of the central opening of the steering wheel that extends toward the center of the central opening. The projection is received by a recess in the surface of the key and follows the shape of the recess when the key is inserted into the cylinder lock. At the same time, the steering wheel is rotated to unlock the cartridge lock. Once the notch provided in the outer edge of the steering wheel is in line with the outer edge notch provided in the intermediate disk of the cylinder lock and is located at the steering bar, the cylinder lock is in an unlocked state. This allows the key to be further rotated to move the latch bolt attached to the cylinder lock, for example. A cylinder lock of this type is disclosed in WO 2013121114.

The cylinder lock disclosed in WO 2013121114 is quite difficult to assemble. The intermediate disc and the turning disc are separate components intended to be inserted into the inner cylinder. The inner cylinder consists of two separate parts. The inner cylinder, the steering disc and the intermediate disc cannot be inserted into the cylindrical casing unless they are held together tightly. If the components are not held together tightly, the spacing of the components provided for the inside of the cylindrical casing is insufficient for the components. In order to properly operate the cylinder lock, this spacing requires dimensional accuracy, i.e., keeps the tolerance as small as possible. Furthermore, if the components are not held together tightly, the components can become separated from each other.

The object of the present invention is to alleviate the above problems. The present invention is based on the concept of holding the steering disc and the intermediate disc against each other without having to try to hold the steering disc and the intermediate disc together; and providing an intermediate disc and steering that does not require an inner cylinder Disc assembly. The object of the invention is achieved as set forth in the scope of the independent patent application. The dependent patent application scope describes various embodiments of the invention.

The cylinder lock of the present invention is provided with a steering disc, an intermediate disc and a steering rod. The steering disk and the intermediate disk include at least one outer edge recess and a central opening. The steering disk also has a projection at the edge of the central opening that extends toward the center of the central opening. The steering disk can be rotated along the axis of the key by a key having at least one curved groove in the surface. The cylinder lock also includes a cylindrical outer casing in which the steering disc, the intermediate disc and the steering rod are housed. Once the steering disk has been rotated in a corresponding manner, the cylinder lock is in an unlocked state such that the outer edge recess of the steering wheel, together with the outer edge recess of the intermediate disk, forms a longitudinal groove at the steering bar. The cylinder lock is otherwise locked. One of the intermediate discs is a module that includes annular recesses on both sides thereof. Thereby, the outer edge of the module and the edge of the central opening respectively have outer ridges And the inner ridge. The inner ridge has a slit on both sides of the module, and further, the module has an intermediate ridge extending from the edge of the central opening toward the center of the central opening. The module has at least one fixed protrusion and a fixing hole on opposite sides thereof. The fixing protrusion and the fixing hole are transverse to the side of the module.

A steering disk is provided in the annular recess on both sides of each module, and further, an intermediate disk is provided on one side of each of the modules. The modules are successively connected by using the fixing protrusions and fixing holes of the module. The modular structure eliminates the need for a separate inner cylinder. Due to the structure of the module, and because the fixed protrusions and the fixing holes hold the modules against each other, the module, the steering disk and the intermediate disk are easily held together, abutted against each other. Therefore, it is very simple to insert the module, the steering disc and the intermediate disc into the cylindrical casing.

The invention is described in more detail below with reference to the drawings in which: FIG. 1 shows an example of a cylinder lock of the present invention, FIG. 2 shows an example of a cylindrical casing of the cylinder lock of the present invention, and FIG. 3 shows the invention by the present invention. An example of an assembly formed by one of the cylinder locks, Figure 4 shows an example of Figure 3 at different angles.

Figure 5 shows an example of a module according to the present invention, Figure 6 shows the module of Figure 5 at different angles, Figure 7 shows another example of a module according to the present invention, and Figure 8 shows the module of Figure 7 at different angles, Figure 9 shows a third example of a module in accordance with the present invention, and Figure 10 shows the module of Figure 9 at different angles.

Figure 1 shows an example of a cylinder lock 1 of the present invention in an exploded view. The cylinder lock is provided with a steering disc 3, intermediate discs 4, 5 and a steering rod 6. The steering disk and the intermediate disk include at least one outer edge recess 4A, 3A, 54 and central openings 4B, 3B, 58. The steering wheel 3 also includes a projection 32 at the edge of the central opening 3B that extends toward the center of the central opening. The intermediate discs 4, 5 are rotatable along the axis of the key by means of a key 14 having at least one curved recess 24 in the surface. The cylinder lock also comprises a cylindrical outer casing 2 in which the steering wheel 3, the intermediate discs 4, 5 and the steering rod 6 are positioned in the assembled state. Once the steering wheel 3 has rotated, the cylinder lock is in an unlocked state such that the outer edge recess 3A of the steering wheel 3 together with the outer disk outer edge recesses 4A, 54 form a longitudinal groove at the steering bar. The cylinder lock is otherwise locked.

As can be seen in Figure 1, one of the intermediate discs is quite different in construction from the known intermediate disc. These intermediate disks form modules 5A, 5B, 5C (Figs. 5 to 10). Each module includes annular recesses 51, 51A on its sides that have an outer ridge 53 at its outer edge and an inner ridge 56 at the edge of the central opening 58. The module also has an intermediate ridge 59 that extends from the edge of the central opening 58 toward the center of the central opening. The intermediate ridge has at least one securing projection 60, 61 and a securing aperture 66, 67 provided on opposite sides of the intermediate ridge. The fixing protrusion and the fixing hole are transverse to the side of the module. The annular recesses 51, 51A receive the steering disc 3 on both sides of each of the modules 5A, 5B, 5C, and the intermediate disc 4 is located on one side of the modules 5A, 5B, 5C, while the components are opposite to each other Assembled with each other. Once the components are assembled, the modules are successively connected by means of their fixing projections 60, 61 and fixing holes 66, 67.

As shown in the figures, the sides of the module 5 and other discs extend laterally to a longitudinal axis A (Fig. 3) formed by the modules and discs joined together. When the module is assembled with the disc In this case, the edge is instead transverse to the side and forms a face parallel to the longitudinal axis A. The fixing projections and the fixing holes can be implemented differently as shown in the drawing, that is, as two fixing projections 60, 61 and two fixing holes 66, 67. For example, the fixing protrusion and the fixing hole may be a disc protrusion and an elongated hole, respectively. The one or more fixed tabs and the one or more securing holes are positioned such that the tabs are provided on one side of the module and the holes are provided in the other side of the module. This allows the modules to be connected one after the other.

Figure 1 also shows that the cylinder lock can be equipped with other components. The cylinder lock 1 can have a steering rod saddle 7 and a spring 8 at the steering rod saddle. The steering rod saddle and spring are intended to move the steering rod 6 to the locked position, i.e., to allow the steering rod 6 to prevent the turning disc and the intermediate disc from rotating. The steering rod saddle and spring can also be replaced by a single spring, for example.

The cylinder lock can also be provided with a protective disc 9 (for example for drilling), an additional front disc 10, an additional rear disc 13 or a combination thereof. The additional front disc can be attached to the module by means of a projection (not shown in the drawings).

Furthermore, the cylinder lock can comprise at least one additional disc 16 . The additional disc affects how the recess 24 of the key 14 controls the rotation of the steering disc by the action of the projection 32 provided on the steering wheel. As is known, the cylinder lock can have a bottom portion 12. When the steering disc outer edge recess 3A is combined with the intermediate disc outer edge recesses 4A, 54 (that is, together with the outer edge recess 54 of the module) to form a longitudinal groove at the steering bar, The bottom portion can be rotated by the key 14. The bottom portion is typically attached to the latch bolt (eg, by a tail piece).

The cylinder lock can also be provided with two lateral bars 11. In this case, the module and the intermediate disc 4 have two other outer edge recesses 55 for the lateral bars. The lateral disc aligns the steering disc, the module and the intermediate disc around the key 14 inserted into the lock, and will rotate when the key is rotated in the cylinder lock The steering disc, the module and the intermediate disc are connected together.

The position of the aforementioned components on the inside of the cylindrical casing 2 can be further promoted by providing the cylinder lock with at least one bundled disk 15. In this case, the outer ridge 53 of the module has at least one inclined surface 65 which is laterally inclined on the outer surface of the outer ridge, that is, at the outer edge of the module. The slope has a tie-like projection 31. The bundled disc 15 has an opening 15A, and the bundled projection 31 can be inserted into the opening 15A of the bundled disc 15. Once the bundled disc or disc is placed in place, it is ensured that successively positioned components are parked on each other.

2 is a more detailed view of an exemplary cylindrical outer casing 2 for use with the cylinder lock of the present invention. As can be seen, the spacing 21 is provided inside the cylindrical casing 2 for the module 5, the turning disc 3, the intermediate disc 4 and any other intermediate discs. In addition, spacings 22, 23 are provided in conjunction with this spacing for the steering rod and steering rod saddle. Also shown in FIG. 2 is a curved groove/groove 24 provided in the surface of the key 14.

Figure 3 shows the modules 5 connected in succession. As described above, the annular recess accommodates the steering disk 3 on both sides of the module, and the intermediate disk is accommodated on one side of the module. As can be seen, the successively connected module outer ridges 53 abut each other. The inner ridge 56 abuts the intermediate disc 5 between the modules. The other end of the bundle includes a bottom portion 12 that is coupled to the module by an additional rear disc 13. As can be seen in Figure 3, the outer face of the outer ridge forms a relatively continuous surface. Since one module 5 incorporates two intermediate disks, there is a relatively small number of module interfaces. The same manner is also applied to the inner ridge 56. Thus, the keyway formed by the module (continuous central opening 58) is particularly continuous compared to the keyway of a known cylinder lock that includes a rotatable steering disk. The keyway has only a different gap at the slits 57, 57A of the inner ridge. A projection 32 that turns to the central opening of the disk is received into the apertures. Therefore, the keyway makes the possibility of shackles smaller. The bundle disclosed above is inserted into the cylinder It is easy to handle when in the outer casing 2.

Figure 4 shows the bundle of Figure 3 at different angles. At least one bundled disc 15 has been added to the bundle. The bundled discs make the bundle even easier to handle. For example, the bundle remains together even if the bundle falls from the hand of a person to the workbench at a small distance. The figure also shows an anti-drilled disc 9 to illustrate how the anti-drilled disc 9 is positioned relative to the bundle. The examples of Figures 3 and 4 also include additional discs 16. The end of the bottom portion 12 contains a shape 41 for a so-called tail piece or latch bolt.

Figures 5 and 6 show examples of modules of the present invention as seen from one side of the module and from the opposite side thereof. Similarly, Figures 7 and 8 show another example of a module, and Figures 9 and 10 show yet another embodiment of the module.

As shown by the example shown in the figures, the intermediate disc positioning recess 53A is provided in the outer ridge of the module. The edge of the intermediate disc 4 has an opposite shape to be received into the positioning recess. This allows the intermediate disc to engage the module, and the module including the steering disc and the intermediate disc can be easily joined together by means of the fixing projection 60 and the fixing hole 66. The intermediate disk may also include at least one hole/slot 4C for the fixed projection 61 of the module, as shown. The intermediate disk may have an intermediate ridge similar to the intermediate ridge 59 of the module. In this embodiment, the intermediate ridge of the intermediate disc has one or more holes or one or more slots for one or more of the mounting tabs.

It is also possible to provide a bottom recess 63 at the bottom of the annular recess 51, 51A of the module. The bottom recess makes the steering wheel 3 relatively easy to rotate by reducing the friction surface and making room for the impurities. The bottom of the annular recesses 51, 51A may also be provided with a hole 62. Further, a lateral recess 64 may be provided on the inner surface of the ridge outside the module. The holes and lateral recesses make the structure lighter and, in addition, provide space for any dust sand that ultimately remains in the cylinder lock.

The module 5 also supports the steering wheel 3 in a different manner than known solutions. According to a known solution, the bearing surface of the steering wheel is the outer edge of the steering wheel, and according to the invention, the bearing surface of the steering wheel 3 is the inner edge of the steering wheel, ie the adjacent module of the central opening 3B The edge of the ridge 56 within 5. Since the bearing surface of the steering disc is the inner edge of the steering disc, it is less susceptible to dust and other impurities entering the cylinder lock. This is due to the fact that in the cylinder lock, dust and other impurities are pulled down by gravity, i.e., away from the bearing surface, which is now not positioned low and instead is positioned at the center of the cylinder lock. Usually, the cylinder lock is installed horizontally. This fact makes the cylinder lock of the present invention more resistant to dust and impurities than prior art solutions.

Figures 5 to 10 show examples of three different modules 5A, 5B, 5C. In the module, the inner ridge cutouts 57, 57A, 57B, 57C, 57D, 58E are provided at different locations on the sides of the module. Thus, the modules can be used with the keys 14 having at least two curved recesses 24. Of course, these modules can also be used with keys that have only one curved groove. It is also possible to create different modules by different positions of the slits on the sides of the module. For example, as shown in FIG. 6, if the module 5A of FIG. 6 has a cut 57A on the right side rather than the left side of the inner ridge 56, the cut will be similarly located in the inner ridge 56 of the module 5A.

9 and 10 also show another exemplary manner of positioning the fixed projections and fixing holes in the module 5C. As can be seen, one or more securing projections 90 and one or more securing apertures 91 can be provided on opposite sides of the outer ridge 53. Thus, it can be explained that it is possible to provide at least one fixing projection and at least one fixing hole on the opposite side of the intermediate ridge 59 and/or on the opposite side of the outer ridge 53.

Therefore, the module functions not only as an intermediate disk but also as a rotation limiter. This means The steering disc does not have completely free rotatability but has a certain limited range of rotation. The slits 57, 57A define a sector shape for the rotatability of the steering disk. The inner ridge 56 at the end of the slit limits the rotation of the steering wheel because the projection 32 of the steering disc is received in the slit.

The structure of the module makes the use of a separate inner cylinder unnecessary because the modules replace the inner cylinder once they are connected to each other. Cylinders having different lengths are simply produced by successively connecting the desired number of modules. A rigid guide for the key 14 is provided when the intermediate ridge 59 of the module forms a continuous longitudinal ridge after successively combining the modules. The grooves created for the steering rod are also stiffer than in prior art cylinder locks, resulting in enhanced anti-theft properties. That is to say, the lock cylinder of the present invention is easy to assemble, more durable and therefore more reliable than known similar solutions.

In light of the above examples, it is apparent that many different solutions for implementing the present invention exist. Thus, the invention is susceptible to numerous different embodiments within the scope of the invention.
